I jacked the car up in the end as i couldnt find the drain plug on the block either.
as there was no room to get to the hose i had to put a 3 inch g clamp on the green clamp and tighten the g clamp, once it started to weep i slid the green clamp up the hose and lowered the car,
the water was well sh!tty, i now have anti freeze, and i changed the thermostat as well cos it was shagged, reno wanted £2 each for the 5 tork bolts that hold it on but i went else where and got 6 for £1 !!
Should be much better now !!
